Inlet gas analyzer for cement plant rotating kiln

The continuous measurement of oxygen and COe (combustibles) in cement plants has always been a challenge for any type of analysing probe. Up to now, it’s been nearly impossible to extract measuring gas for continuous analysing systems, because the probe becomes “cemented over and sealed” very quickly, resulting in extremely high maintenance costs and kiln production down time. Now ENOTEC has solved these special analysing problems in the cement industry with the new analysing system called CEMTEC®. Now Cement plants are able to significantly reduce their maintenance costs to a fraction of their previous costs. Mounted in a water-cooled outer jacket, the measuring probe is continuously turning +/- 90°. This keeps the gas inlet area free of cement and prevents the dust build up on the probe filter. Additionally, a highly effective automatic cleaning system with pressurised air ensures that the probe with its dust filter and the gas channels remain completely clean and clear. The InSitu probe measures oxygen using a ZrO2 cell and the COe concentration with a Ga2O3 sensor. The system delivers 2 continuous measuring signals with a response time less than 1 second. In addition, it is also possible to extract flue gas for the extractive type flue gas analysis (SO2, NOx, etc.).
